Abstract
This study investigated the effects of exogenous hydrogen sulfide on the ascorbate and glutathione metabolism in wheat seedlings leaves under copper stress. The results showed that copper stress induced the increases in the activities of APX, DHAR, MDHAR, GR, GalLDH and gama-ECS, and the contents of AsA, GSH, total ascorbate and total glutathione. Pretreatment with sodium hydrosulfide (NaHS), a hydrogen sulfide (H2S) donor, enhanced the activities of GR, DHAR, GalLDH and gama-ECS, and the contents of AsA, GSH, total ascorbate and total glutathione under copper stress. Meanwhile, pretreatment with NaHS decreased the malondialdehyde content and electrolyte leakage induced by copper stress in plants. Our results suggested that exogenous hydrogen sulfide alleviated oxidative damage by regulating the ascorbate and glutathione metabolism under copper stress, and H2S has important role for acquisition of copper stress tolerance in wheat seedlings. Therefore, exogenous hydrogen sulfide can be used as a regulator to improve crop tolerance under copper stress.
